My boyfriend bought me this cup as part of a gift set for Christmas and it's amazing. My tea stays hot for so much longer than in a regular mug, and the lid is the handiest little accessory. Its even got room for me to leave my teaspoon in the cup (without the infuser basket) and still leave the lid on! I love it!
I recently dropped and broke my Pistachio cup that my mom gave me as a gift and was devastated! Use it several times a day so I immediately got another. It keeps tea so hot and just makes the ritual of making a cup, so wonderful. You will not be sorry!
